My invention relates to tubular watch cases of the type described in my United States Letters Patent No. 1,891,611, issued December 20, 1932.

My invention has for its object to provide a construction which is cheaper to manufacture than that shown in the said patent and which will lend itself readily to being combined with a lighting mechanism, lip stick, pencil, etc. As described in the said patent, the movement is slid into the tube from one end.

In my present invention the principal object is to preferably form the case of a number of tubular sections or portions which may be telescoped into a tube or otherwise secured thereto to hold them securely in place. The movement is located in one of the tubular portions. In this construction the movement can be placed in one of the tubular portions, the others secured to or around it, or an enclosing tube may be slipped over the assembled parts holding them firmly in place.

Other objects will appear from the hereinafter contained description and claims.

My means of accomplishing the foregoing objects may be more readily understood by having reference to the accompanying drawings which are hereunto annexed and are a part of this specification, in which- Fig. 1 is a front elevation of the case combined with a lighter showing the case closed;

Similar reference numerals refer to similar parts throughout the entire description.

As shown in the drawings, Figs. 1 to '7, the case is formed of tubular sections or portions I,

2, 3 and 4.

The section 1 contains a lighting pose the face 6 of the watch movement.

The

upper end of the section 3 is closed by a disc I which extends outwardly over the cut-away portion, the disc I being of the same diameter as the tube out of which the section 3 is formed. Within the space formed by the cut-out portion I mount the section 4 which contains the watch movement W as clearly seen in Fig. 4.

The ends of the section 4 are closed by discs 8 and 9 which are provided with central threaded apertures to receive screws [0 and II. The

tubing forming section 4 is of sufficiently small diameter to rotate freely inside of the section 3.

The central portion of section 4 is cut away and is fitted with a crystal I2 which covers the face of the movement. The remaining portion of the wall of section 4 which is in register with the crystal l2 comprises a knurled portion I3, the knurling being to facilitate the rotation of the section 4. His obvious that when the knurled portion is presented, as shown in Fig. 1, that the crystal is protected by the rear wall of the section 3.

It will be apparent fromthe foregoing description that all that is necessary to do if one desires to remove the movement is to take out the two screws l0 and II, when the section 4 will drop out of the section 3 and by removing the disc 8 easy access is afiorded to the movement. Preferably the disc 9 is soldered in position though,

if desired, it can be frictionally held, as is the disc 8.

In Figs. 8 to 16 inclusive, I have shown a modified form of construction in which the case is formed of three tubular sections or portions 20, 2| and 22. The section as clearly seen in Fig. 10 comprises a container for a lip stick which is of the common standard form and is adapted to telescope inside of the tubular section 2 I This section 2| has a cut-out portion which exposes the face 23 of the movement. The movement is mounted in the tubular section 22 as clearly seen in the detailed views. The upper end is closed by a disc 24 which closes the tube, the diameter of the disc 24 being the same as the outside diameter of the tube forming section 2| The lower end of the section 22 is preferably closed by means of a flanged disc 25 to which is secured, preferably by means of a rivet 26, a flanged disc 21 wh ch is of slightly larger diameter than the tube forming the section 22, the rear 28 of the section 22 being preferably knurled as clearly seen in the detail views. This knurled portion may be, if desired, provided with the smoothed portion 2| similar to the corresponding portion 2' in the other views, and on which may be engraved a monogram if desired. That portion of the section 22, which covers the face 23 of the movement, is closed by a crystal 29.

A slot 30 is cut in the top of the section 2| to permit the passage of the crown stem 3| when the section 22 is being inserted into the section 2|.

The result of this construction is that when the section 22 is telescoped in the section 2|, the flanged disc 21 exerts sufficient frictional pressure against the wall of the tubular section 2| to hold the disc against rotation thereby permitting the section 22 to be freely rotated upon the pivot 26.

As shown in Figs. 17 to 20 inclusive, and in Fig. 22, the case is made up of tubular sections 30, 3|, 32 and 33; as illustrated the section 30 is provided with lighting mechanism which is adapted to telescope the lower portion of the section 3|. In some instances it may be found desirable to reverse the position of this lighting mechanism as shown in Fig. 21 and mount a pencil attachment 34 on it. The section 3| is adapted to telescope the shoulder 35 on the section 30 and to receive at its upper end the lower end of the section 32. This movement containing portion or section 32 comprising a tubular portion closed at its upper end and provided with a cut-away portion in which is mounted the crystal 36 opposite the face 31 of the movement. The section 32 has its rear wall cut away and a segmental section 38 is fitted thereto. A screw 38a having its head projecting slightly beyond the periphery of a plug 381), which constitutes the top of the section 32, forms means for engaging a stop wire 38c, carried by and movable with the section 33, said wire sliding in a groove 38c formed vertically along the surface of 32. This stop prevents complete disengagement of the cover, constituted by section 33, from the section 32, in the normal operation of the cover. However, when necessary, such complete disengagement of the cover 33 may be effected by inserting a screwdriver through a hole 38d and removing screw 38a. Union of the sections 3| and 32 may be effected by screw 32a, which traverses 3| and 32 and takes into a block 32b, spanning the section 32.

A slot 39 is formed in the wall of the section 33 to permit the crown stem to pass therethrough. To look at the watch in this form of case one slides the section 33 upwardly until the face 31 of the movement is exposed. By constructing the section 32 in the manner described it is obvious that I have materially cheapened the construction and made it possible to mount the movement with a minimum of expense. Monogram plates 3| may be applied to or formed upon the sections 3|, as indicated.

As shown in Figs. 23 to 27 inclusive I have provided a simple form of construction for the movement containing section. As shown in these figures, the case comprises sections 40, 4| and 42. The section 4| contains the movement and has discs 43 and 44 closing the ends thereof. These discs are held in place by means of screws 45 and 46. This section is also provided with a cut-out portion in which is mounted a suitable crystal 4'! to expose the face of the movement. In this construction the section 4| is held against rotation by means of springs 48 and 49 which are preferably formed of piano wire and are fitted to a groove 50 formed in the section 4|. These springs provide sufficlent frictional engagement to assist in preventing the sections 40 and 42 from sliding oif of the section 4|. A hole 5| is provided adjacent the top of the section 42 for the insertion of a screwdriver to remove the screw 46. A similar hole 52 is provided in the section 40 in such a location that it will register with the screw 45 when it is desired to remove it. It will be apparent from the foregoing description that I have provided an extremely inexpensive section for mounting the movement, the tubular portion 4| holding said movement being formed in halves which are held together by the telescoping tubular end sections 40 and 42.

Having described my invention what I regard as new and desire to secure by Letters Patent 15 1.
